Parsing Configuration File

Please show an example of how I can parse this file into an array in PHP. The ideal output would be the equivalent of making this array (not all values are shown in the example):

array("unlocks" => array(
 "Sprint_Mki" => "1",
 "Sprout_Collect" => "1"
),
"experience" => array(
 "Lumbering" => "36"
));

NB: The configuration file will change to have more values in and the script must accommodate for these changes.

"Out"
{
	"unlocks"
	{
		"Sprint_Mki"		"1"
		"Sprout_Collect"		"1"
		"Grain_Planting"		"1"
		"Sprout_Planting"		"1"
	}
	"experience"
	{
		"Lumbering"		"36"
		"Planting"		"24"
		"Survival"		"0"
		"Mining"		"0"
		"Harvesting"		"24"
		"Weapon_Crafting"		"0"
	}
	"date"		"Monday 02/22/10"
	"skills"
	{
		"Lumbering"		"8"
		"Planting"		"6"
		"Survival"		"6"
		"Mining"		"8"
		"Harvesting"		"6"
		"Weapon_Crafting"		"2"
	}
	"name"		"James"
}
